Given numbers are 306, 440, 619, 810

The list of prime factors of all numbers are

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 619 are 619

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 306, 440, 619, 810

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(306, 440) = 67320

GCD(306, 440) = ( 306 x 440 ) / 67320

= 306 / 440

= 306

Step2:

LCM(2, 619) = 1238

GCD(2, 619) = ( 2 x 619 ) / 1238

= 2 / 619

= 2

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 306, 440, 619, 810 is 1
